MOTOR-DRIVEN GEARING.

Specification of Letters Patent.

Patented June 1, 1920.

Application filed July 29, 1918. Serial lfTo. 247,199.

To all whom it may concern:

Be it known that I, WILLIAM JnMEs GEoRonsoN, a citizen of Greece, and resident of Oneonta, in the county of Otsego and State of New York, have invented certain new and useful Improvements in Motor- Driven Gearing, of which the following is a specification.

T his invention relates to the class of agitators, and more particularly to drink mixers designed to be used in connection with soda fountains, or the like, for preparing various mixed drinks. I T

The primary object of the invention is to provide a novel device of the above character in the form of a double drink mixer whereby a plurality of drinks may be mixed at the same time, the parts being constructed in a novel manner so as to facilitate the application and removal of the receptacle or glass containing the drink, and for s1multaneously driving two agitators, as will be hereinafter more fully set forth.

With the above and other objects in view, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described herein and set forth with particularity in the claims appended hereto.

Reference is had to the accompanying drawings forming a part of this application,

in which like reference characters indicate the corresponding parts throughout the several views, in which- Figure 1 is a front elevation of one form ofthe improved double drink mixer constructed in accordance with my invention,

Fig. 2 is a plan view thereof,

Fig. 3 is a vertical cross section taken through one of the containers and showing the mounting of the dasher,

Fig. 4: is a horizontal cross sectional view taken on the line 4- 1 of Fig. 3,

v Fig. 5 is a disassembled perspective view of a dasher shaft and its mounting,

Fig. 6 is a vertical sectional view showing a modified form of the device, in which the agitators operate through the bottom of the containers instead of from the top thereof, and

Fig. 7 is a plan view of the device shown in Fig. 6 with the containers removed.

Referring to the drawings in detail, and more particularly to the form of the invention illustrated in Figs. 1 to 5 inclusive, my improved double drink mixer is shown as comprising a base 10 having arranged thereon a permanent standard 11 disposed intermediately between the ends of the base 10 and carrying a motor 12 arranged in a suitable casing provided with a handle 13 for conveying the device from place to place and having flexible connections 14 leading to the motor from a suitable source of energy so that the motor will be electrically operated.

Rigidly supported in a horizontal position by the standard 11 is a pair of spaced par allel plates 15, the same accommodating the shaft 16 of the motor which has a gear 17 mounted thereon between the plates, the plates being secured in fixed relation as shown at 18. The plates are positioned in spaced relation below the motor casing and immediately above the glasses or other containers indicated at 19, as designed to be placed upon the base 10 in the act of mixing the various drinks.

The dashers for agitating the drinks are indicated at 20, the same being in the form of vertical shafts carrying suitable agitating projections 21 on their lower ends designed to enter the glasses or containers 19,

which are held by suitable clamping members or arms 22 of a resilient nature carried by uprights 23 arranged upon the base for this purpose. Each dasher staff or shaft 20 is provided with an enlarged squared portion 24: near its upper end, received within a sleeve 25 having a square bore 26 and an enlargement 27 provided with a peripheral notch 28 for the purpose of detachably fixing pinions or gears 29 thereto between the respective plates 15.. Suitable keys 30 are provided for connecting the pinions 29 with the sleeve 25, although it is obvious that any other suitable detachable fixing means may be employed if desired. The pinions 29 are also disposed in mesh with the pinion or gear 17, so as to be simultaneously rotated for rotating both agitating or dasher shafts for the purpose of mixing the various drinks, a plurality at a time. To permit the placing and removal of the container or glass, the shafts 20 are made vertically slidable in the squared portions of the sleeves 25 and are provided with operating knobs or handles 31 on their upper ends capable of detachment and forming shoulders as indi- 34, suitable electrical connecting wires 35 being arranged to carry the current to the motor, while as in the previous form, suitable means are provided for closing the circuits when the device is to be used. The motor shaft is indicated at 86, extending upwardly from the motor, while the casing 84 is designed to support a pair of spaced plates 37, corresponding to the plates 15, in that they are held in spaced parallel relation and secured together, as shown at 38.

Arranged upon the shaft 36 is a gear or pinion 39 suitably fixed thereto and adapted to mesh with pinions or gears 40 removably mounted upon sleeves 41 ournaled between the spaced plates, so that the pinions or gears 40 will mesh with the pinion or gear 39. The plates are also provided with vertically alined openings corresponding to the bores of the sleeves 41, so as to receive the squared lower ends of shafts 42, I which shafts have detachably secured to their upper ends containers or glasses43, through which the shafts rotate in the form of dashers at the bottoms of the glasses, or containers, suitable agitating means 44 being provided on the upper ends of the shafts as shown. The base portions 45 of the containers are held from rotation by engagement with pins or stops 46, so that when the motor is started and the containers are applied by engaging the depending squared lower portions of the shafts 42 in the squared portions of the sleeves 41, both agispecific structure, I desire that it be understood that such changes may be made in said structure as do not depart from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is new, and desire to secure by Letters Patent, is:

1. In combination a base, a motor casing supported thereon having a vertical shaft, a pair of spaced plates receiving said shaft, a gear fixed to said shaft and located between said plates, gears journaled between the plates in mesh with the first mentioned gear and provided with polygonal bores, cylindrical. shafts movable axially through the bores of the gears and provided with an enlarged polygonal upper terminal adapted to snugly lit the polygonal bores of the gears to establish a driving connection therewith, the cylindrical body portions of the shaft being movable into the polygonal bores of the gears to permit rotation of the latter independently of the shafts, and handle knobs carried by the upper terminals of the shafts limiting the downward movement of the latter through the gears.

2. In combination a base, a motor supported thereon provided with a drive gear, a pair of spaced bearing plates supported above the base and receiving the drive gear, sleeves provided with reduced terminals journaled in and confined between the plates and provided with polygonal bores, demountable driven gears non-rotatably secured to the sleeves between the plates and permanently meshing with the drive gear, axially movable shafts mounted in the bores of the driven gears having cylindrical body portions and enlarged polygonal terminals adapted to snugly fit the polygonal bores of the driven gears to establish a driving connection therewith, the shafts being movable to elevated position to dispose the cylindrical portions thereof within the polygonal bores topermit independent rotation of the driven gears with relation to the shafts, and handle knobs carried by the upper terminals of the shafts for limiting the axial movement of the polygonal-portions of the shafts through the sleeves.

In testimony whereof I afiix my signature hereto.

WILLIAM JAMES GEORGESON.
